Tourmaline

tour·ma·line | ˈtu̇r-mə-lən

noun

A semi-precious gemstone that can take on multiple colors and consists of a complex borosilicate

Tourmaline is a type of semi-precious gemstone, a silicate of boron that has been compounded with other elements such as potassium, sodium, iron, and aluminum. It can take on a number of naturally occurring colors and is commonly used in jewelry. The watermelon tourmaline in particular is very popular because it is pink on one end, white in the middle and green on the other end, giving a unique set of colors that is not found naturally in other types of minerals. Tourmaline has a history of use in scientific experimentation, but today is primarily used for jewelry.
